While the recession has put a damper on development along San Francisco’s Octavia Boulevard, the mayor’s office has reached out to Douglas Burnham of Envelope A+D to come up with something cool to temporarily fill the two vacant lots that front Hayes Green at the intersection of Octavia and Fell.

Burnham’s plan sounds like a lot of fun. He plans to transform the space into a mini-shopping, dining, and entertainment destination called PROXY–using a series of modular units that will be recyclable in two or three years when things ratchet up again. The vision includes a group of pop-up stores, a food court served by “slow food” carts, an art gallery, and a courtyard for projecting outdoor movies. Design-wise, the spaces will make their transient nature apparent, revealing their infrastructure (e.g., wiring, water storage) and their modular assembly.
